Abstract:
The Global Emissions Inventory Activity (GEIA) is an activity of the International Global Atmospheric Chemistry (IGAC) Core Project of the International Geosphere-Biosphere Program (IGBP). The focus of GEIA is to make global emissions available on a one degree grid.

A global data base of black carbon emissions to the atmosphere from fossil fuel combustion has been compiled for atmospheric ... chemistry and climate studies. The data base is on a 1 x 1 degree latitude/longitude grid and is based on the work of Matthews (1983), Lerner et al. (1988), and Dignon (1992). The original work of Penner et al. (1993) provides the emissions inventory data on a 5 x 5 degree grid.

Units of emission yield a global total of 12.6 TgC/y and are given as the mass in metric tons of carbon for each 1 x 1 degree grid cell. The emissions are expected to represent the emissions for a typical mid-1980's year. The distribution is based on national totals and then mapped to a 1 x 1 degree grid according to the updated population mapping of Logan (1993).
